ESA’s Architecture for Exploration Study (AES) is overviewed in Lunar Base Quarterly 1/2008 (EDIT: to be clear, the Quarterly was released in January):
Lots of Ariane 5, Angara and Soyuz launches with space docking, a space station in Earth-Lunar L1 and many new crewed and non-crewed craft and capabilities.
They had a red team / blue team approach at this point.
